How to kill a demilich?

[neptune]

That's annoying. I have a fear of viruses and junk mail so that's why I didn't join for a while. It doesn't feel good to be in the game a while and be known as a newbie in this. By the way, we're going offtopic. My ways of killing demiliches are: 39 at least clawing, Multiple banishments, or just don't kill them(I was in stoneville and I went to the kobold filled cave and I saw a demilich. Those things kinda freak me out. But what freaks me out more is the giant rat animation. Went past it and it knocked down 100 of my hp!
